with low no refrigerent this will occur ...put 12 oz of r134 into the system,,, if low ,,,and see if you have a leak ....if no leaks look at the compressor for oil leakage ...if leaking and you have low refrigerent you must install pag 150 refrigerent oil of about 4 oz , this will help seal/lubricate the system and may stop the loss of refrigerent ..
with 80 deg f charged properly you should get 40psi low side pressure ...fans on high , rpm at 1200 ....doors open ...
better too little refrigerent that too much ...oil is ok to have a little extra...
